and match car pieces and evolve their vehicle by testing on one of the race tracks Supporting multiplayer Car Genesis allows players to interact on the race track and test their vehicle against other opponents B Camera Position The player will be able to toggle between first and third person views using the tab key C User Interface Design 1 User Interface Description a The title screen features a game inspired background and set of buttons that allow the player to customize their car start a new single player or multiplayer game join an existing multiplayer game change game options or exit the game b A message is displayed when the user has passed the wrong checkpoint This will indicate that the user has missed a checkpoint or is headed in the wrong direction c The message in the upper left corner displays if the game is waiting for other players and when the race is about to start It also displays when players leave or join the race d The box in the upper right corner keep the user informed of time laps completed total laps e The speedometer in the lower right corner displays the player s current speed 4 2 Key Screen Images Main Menu 5 In game interface first person view Car

should be able to use one to control their car Torque treats game controllers as joysticks so the same scripting that is used to handle joystick and racing wheel input should also support game controllers 6 Other Any input device not mentioned here can still conceivably be used to control the car as long as it behaves similarly to one of the above input devices and identifies itself to Windows as one of those device types E Replaying and Saving In single player mode the player may choose to race on any track at any time and may replay any track as many times as he or she desires Because there is no order in which the tracks must be completed there is no need to save the player s progress In both single player and multiplayer mode the player s car configuration persists until he or she exists the game 7 F Level Summary 1 Desert Race This track was designed as a somewhat short course that intermixed tight curves and small straightaways It tests both the speed and handling of the vehicle 2 Dusk Race This track was designed as a larger course than the desert track Intermixed tight and wide curves multiple level hills along with larger stretches of straightaways allow the user to test the vehicle under more intensive and enduring circumstances 3 Motor Fairway This track was designed as a large loop track The straightaways are long and the curves are exceptionally wide to test the maximum speed of the vehicle II Artificial Intelligence A Opponent AI There are no AI controlled opponents B Player Detection Checkpoints are placed around the track to ensure that players are following the correct path and to calculate when the player has finished a lap or finished the race Each checkpoint has a trigger that detects when player has crossed the checkpoint C Motion Based on the parameters defined for each part and the car as a whole the Torque game engine is able to simulate vehicle physics in a reasonably realistic manner D Collisions The base that the various car parts are attached to has an invisible mesh that encompasses itself and as well as the area that the other parts occupy This is used by the game engine to detect collisions with objects and other players E Combat Car Genesis is intended to be solely about racing so cars cannot become damaged and there is no direct combat Despite the lack of direct combat it is possible that players can utilize their entire car as a weapon by either attempting to drive in way that prevents opponents from passing or by deliberately ramming an opponent to force him or her to miss a checkpoint or to get out of the way III Game Elements 8 A Items 1 Car Base A model to which all of the parts are attached It consists of little more than a simplified chassis a seat and steering wheel and mount points for other parts The base is the same for all cars and does not affect the cars attributes 2 Body Parts A set of fronts middles and backs each with unique attributes The player selects one from each category and the sum of the part attributes helps determine the overall car attributes such as engine torque mass drag and top speed 3 Wheels A set of wheels for the car Different wheels produce different amounts of friction when they contact the ground as well as affecting the sensitivity of the car s steering and its top speed B Character Bible 1 Driver A male or female driver which can be selected on the car customization screen The driver has no name or backstory and does not affect the car s performance in any way IV Story Overview A Background Plot Summary All across the country there exist elite groups of underground racers Not content to simply perform basic customizations on their cars they mix and match entire sections of
